Allegro’s hydrocelin treatment for osteoarthritis has demonstrated a satisfactory safety profile, giving it potential to become a leading disease-modifying treatment for osteoarthritis. This was announced at the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (WCO) in Rome, Italy.

The product, known as microparticle hydrogel hydrocelin, was announced as being non-pyrogenic following a series of preclinical tests into various safety aspects including irritation, delayed sensitisation and systemic toxicity.

Hydrocelin is intended to provide pain relief, protect cartilage and promote joint homeostasis, improving quality of life for osteoarthritis patients. It contains cross-linked microparticles that are designed to act as tiny shock absorbers in the synovial fluid of the affected joints. It is administered by an injection once annually, making it minimally-invasive.

As part of the biomedical company’s focus on generative joint disease, the hydrocelin treatment is one of Allegro’s leading nanotechnology-based therapeutics.

Subsequently, a clinical trial of the treatment in osteoarthritis patients is anticipated to take place later this year.

CEO at Allegro, Lucas Decuypere, commented on the positive results and upcoming trial: “The unique cross-linking properties of hydrocelin make us believe there is huge potential to help alleviate the pain and suffering of people with osteoarthritis. As Allegro’s next milestone is the start of a pivotal trial in patients, which we expect later this year, we hope to quickly see our vision confirmed.”
